RTSP Cache Redirection
Alteon supports cache redirection for Real Time Streaming Protocol (RTSP). RTSP cache redirection
is similar to HTTP cache redirection. Multimedia presentations consume a lot of Internet bandwidth.
The quality of these presentations depends upon the real-time delivery of the data. To ensure the
high quality of multimedia presentations, several caching servers are needed to cache the
multimedia data locally. This data is then made available quickly from the cache memory as
required.
RTSP cache redirection redirects cached data transparently and balances the load among the cache
servers. If there is no cache server, the request is directed to the origin server. Internet Service
Providers (ISPs) use this feature to cache the multimedia data of a customer site locally. Since the
requests for this data are directed to the local cache, they are served faster.
This section explains Layer 4 support for RTSP Streaming Cache Redirection. For detailed
information on two prominent commercial RTSP servers (Real Player and QuickTime), see Real Time
Streaming Protocol SLB, page 291.
You can also configure Alteon to redirect client requests based on URL content. For information on
Layer 7 RTSP Streaming Cache Redirection, see RTSP Streaming Cache Redirection, page 477
